Stage 3

Laminating

Corners and bandaging
Lay a 200mm square piece of mat on the roof deck and ‘wet out’ on both
sides with resin (see hardener addition chart) using a 70mm application
roller. Place the mat onto the face of the adjoining trims with the bottom
edge on the radius of the trim. Fold around the corner and fold over the
top of the trim down on to the deck. It will be easier to dress and feather if
the mat is cut vertically from the top corner of the trim upwards. Using the
70mm roller, 50mm laminating brush and small consolidating roller, feather the corners into place. Any joint in the trims should be bandaged
using the same mix of resin. If any boards are not completely engaged these joins should be bandaged, even a small gap may cause resin to
leak through the boards which will lead to porosity in the laminate.

If any nails holding the trims are not going to be covered with laminate on the deck or corners they should be laminated with a small piece of mat.

The deck of the roof can be laminated before the corners and bandages have cured.

Bandaging for all other details can be completed as outlined in the GRP Edge Trim section.

Laying the main laminate
Unroll 1m of previously cut mat along the lowest part of the roof and align so it
can be unrolled across the roof without running off-line. Carefully roll the mat back.

To get a ratio of 3:1 one-third Cure It Roofing Resin (with hardener added) should be applied on the board and two thirds resin and hardener
on the mat dip the 140mm application roller into the bucket of resin. Lift the roller out of the bucket and without letting the excess run off,
drop 3 rollers full onto the board and coat 1 square metre. This will ensure that there is a ratio of one-third resin on the board.

Unroll the mat onto the Cure It Roofing Resin coated board. In strips of 140mm (1 roller width) wet out the mat by dropping 1 roller full in the
middle of each 140mm run, push the roller away to the end of the 1 metre run, then pull back over the full 1 metre (figure 4.)

Continue across the 1m² (approximately 6 runs) and then roll the roller over the whole area again to ensure good even coverage.

Wet out the next 1m² of board in the same way, remembering to use one third of the Cure It Roofing Resin on the board and two
thirds of resin on the mat. Roll out the mat over the next 1m² of wet out board and continue to roll out the Cure It Roofing Resin as
previously described.

Note:
• Never attempt to lay a roof in wet weather or when wet
  weather is forecast.
• If it starts to rain while you are laying a roof, the roof must be
  covered and must not get wet, always keep a large visqueen
  sheet on site to cover the roof. The visqueen will not bond to

  the curing laminate
• If rain is forecast while laying boards, the boards can be

  temporarily sealed with a coating of resin. Always ensure that
  as much of the roof is covered as possible, ensure that edges,
  or areas of possible water ingress are covered.
• If decking has become damp, do not attempt to lay laminate
  on top.
• Always ensure that the surface you are laying onto is completely

dry and free from debris before you start. A wet surface can lead
to delamination

Note: Avoid spillages by masking off the roof properly,

a fine spray is caused when using the consolidator roller,

wind can carry this a considerable distance. It is important
to ensure that this is considered before the resin is used

on the roof. When resin has cured, there is no easy way
of removing it from car paintwork without damaging the

paintwork. (see spillages in the troubleshooting section.)

YOU MUST FOLLOW THESE INSTRUCTIONS TO

GAIN THE CORRECT RATIO OF RESIN TO GLASS.

Any other protrusions such as pipes, skylights or other

potential weakspots should also be laminated around/over

at this point.
Any joints between trim lengths are bandaged over.

A polyester roller is used to apply the resin to the
